A Digital Filter Bank for The Reconstruction of Uniformly sampled signals from nonuniform samples

摘要

The principle of the reconstruction of uniformly sampled signals from nonuniform samples has been proposed. However no actual design for digital filter banks which are used for the reconstruction is given. This report proposes a design method for such digital filter banks. First, we derive the transfer functions in the digital filter banks from analog counterparts. Next, we realize the resultant transfer functions as DFT modulation filter banks with fractional delay elements. The design cost of the proposed structures is low because of the characteristic of DFT modulation filter banks. Finally, simulation results are shown to confirm the effectiveness of the proposed scheme.
